<P>PROBLEM TO BE SOLVED: To provide an inkjet head equipped with a cylindrical tube formed with high accuracy and density. Ž<P>SOLUTION: The inkjet head has a plurality of cylindrical tubes 5, a piezoelectric element 6, a fixing plate 3, and a nozzle plate 1. The cylindrical tube 5 consists of glass, to the inside of which ink is fed from the one end 5b thereof. The piezoelectric element 6 is used for applying pressure to the ink in the cylindrical tube 5 by deforming the outer wall 5d of the cylindrical tube 5, and is installed in the outer wall 5d of the cylindrical tube 5. In the fixing plate 3, a plurality of holes 4 into which other end 5c of the cylindrical tube 5 is inserted for fixation are formed with a predetermined pitch P3. The nozzle plate 1 is provided with two or more nozzles 2 in the positions corresponding to the positions where the holes 4 of the fixing plate 3 have been formed and is laminated on the fixing plate 3.
